I2C 4 Channel 3.3V to 5V Bi-Directional Logic Level Converter (4 Channel Logic Level Shifter Module)

The I2C 4 Channel 3.3V to 5V Bi-Directional Logic Level Converter is a compact voltage level shifting module designed to safely interface devices operating at different logic voltages. It provides four independent bidirectional channels that automatically translate logic signals between low-voltage and high-voltage systems without requiring direction control. Commonly used for I2C communication, the module is also suitable for UART, SPI, GPIO, 1-Wire, and other digital interfaces. It is compatible with Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and other 3.3V or 5V development platforms.
